Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573846, here are decompositions:

23 + 31573823 = 31573846
53 + 31573793 = 31573846
89 + 31573757 = 31573846
149 + 31573697 = 31573846
167 + 31573679 = 31573846
263 + 31573583 = 31573846
347 + 31573499 = 31573846
383 + 31573463 = 31573846

Showing the first eight; more decompositions exist.
